'nn'risxrnnme on. SANDING DEVICE.

Application filed September To all whom it may concern:

Be it known that I, LoUIs J. V. E. NIEL- SEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Antiskidding or Sanding Devices, of which the following is a specification.

This invention relates to an anti-skidding or sanding device adapted for attachment to motor vehicles, and an object of the invention is to provide means, which may be carried by a motor vehicle, in operative position, at all times, so as to permit the operation thereof to prevent skidding of the vehicle when unexpected requirements for anti-skid means arise.

Another object of this invention is to provide a device as specified which comprises means for depositing sand on the roadway directly in front of the drive wheels of a motor vehicle to prevent skidding of the wheels, and also to eliminate the inconven iences contingent with antiskid devices present approved types.

Other objects of the invention will appear in the following detailed description taken in connection with the accompanying drawing wherein Fig. 1 is a front elevation of the improved anti-skid or sanding device.

Fig. 2 is a slde elevation of the sanding device.

Fig. 3 is a vertical section through the sanding device.

Referring more particularly to the drawings, the invention comprises a storage tank 1 which may be attached to the vehicle at any convenient or desired location. An outlet pipe 2 is carried by the center of the bottom of the tank 1, and the bottom 3 of the tank inclines towards the outlet pipe 2 so that all of the sand may be drained from the tank or receptacle. A pair of branch pipes 4; and 5 are connected to the lower end of the outlet pipe 2, and they extend downwardly and outwardly, so as to position their down turned ends 6 in front of the drive wheels of the vehicle upon which the device is mounted. Removable nozzles 7 are attached by bayonet slot and pin connections as shown at 8 to the down turned ends 6 of the pipes 4. and 5. The nozzles 7 are interchangeable, so as to permit nozzles of the proper width, in accordance with the di- 15, 1923. Serial No. 662,894.

.ameter of the tires of the vehicle to be attached to the down turned ends.

A valve 9 is mounted within the outlet pipe 2 and is pivotally connected to the outlet pipe by the rod 10 which supports the valve. An arm 11 is connected to one end .of therod 10 outwardly of the outlet pipe 2 and it is connected by a rod, or flexible member 12 to a foot pedal 13 which may be either the clutch pedal of the motor vehicle or an independent pedal provided exclusively for the operation of the valve 9 to permit applying of sand to the roadway in front of the drive wheels of the vehicle equipped with the device. A second arm 14 is carried by the rod 10 and it has a s ring 15 connected thereto which is connecte to a suitable ear 16 carried by the tank or rece tacle 1 and is provided for returning t e valve 9 to its normal closed position after release of pressure on the pedal 13.

A set screw 17 is adjustably carried by a. suitable supporting bracket 18, and the setscrew- 17 is adjustable to permit regulation of the amplitude of movement of the arm 11 and consequently regulate the distance the valve 9 is to open for in turn regulatin the quantity of sand or analogous materia delivered by the antiskidding or sanding device.

It is, of course, to be understood that the invention may be constructed in other manners and the parts associated in different relations and, therefore, I do not desire to be limitedin any manner except as set forth in the claims hereunto appended.

Having thus described my invention what I claim is 1. An anti-skid or sanding device for motor vehicles comprising a receptacle, an outlet pipe, branch pipes communicating wit said outlet pipe and being spaced to deposit material in front of the drive wheels of a motor vehicle, a valve in said outlet pipe, a spring connected to said valve for closing the valve, said valve mounted for rocking movement, a. transversely extending arm connected to said valve, operatin means connected to said arm, and adjusta le means for engagement with said arm for limiting the movement of the valve.

2. An anti-skid, or sanding device for mo tor vehicles comprising a receptacle, an outlet pipe, branch pipes communicating with said outlet pipe and being spaced to deposit material in front of the drive Wheels of a engagement With said arm for limiting the motor vehicle, a valve in said outlet-pipe, a. movement of the valve, a second arm conspring connected to said valve for closing' nected to said valve, and a spring connected 10 the valve, said valve mounted for rocking to said second arm for returning the valve movement, a transversely extending arm to closed position.
